Abstract

Phase equilibrium data for 1-propanol + manganese sulphate and 2-propanol + lithium sulphate aqueous two-phase systems were measured at T = 298.15, 308.15 and 318.15 K. The salting-out effect was discussed on the bases of the salting-out coefficient of the Setschenow-type equation. Furthermore, the experimental tie-line compositions were successfully correlated to the generalized electrolyte-NRTL model for mixed solvent electrolyte system (e-NRTL), and the binary interaction parameters of the e-NRTL model were obtained. Correlation of the tie-lines data shows that the calculated values and experimental data are in good agreement and the performance of the e-NRTL model in the correlation of the tie-lines data is good.

► Tie-line data for 1-propanol + manganese sulphate + water system were reported. ► Tie-line data for 2-propanol + lithium sulphate + water system were reported. ► Effect of temperature on the phase equilibrium was discussed. ► The salting-out effect was discussed using the Setschenow-type equation. ► The experimental tie-lines data were correlated to the e-NRTL model.
